Abstract (en)
[origin: US4726547A] A helicopter having the usual tiltable, vertical thrust and lift producing rotor, a separate forward thrust producing propeller as well as provisions for yaw control and compensation is improved in that the propeller is constructed as unshrouded propulsion device. A pair of flow deflecting rudders is arranged downstream from the propeller and symmetrically to both sides of the craft; a frame on the tail portion of the craft includes vertical shafts for pivotally mounting the rudders. A T shaped support structure in the frame includes regular elevational, horizontally extending stabilizer fins and carrier arms. An elevator is arranged upstream from the propeller and from one of the elevational stabilizer fins. The elevator reaches laterally beyond and longitudinally alongside the one fin or beyond a circle provided by the propeller.
